Flame Detection Method Based on Improved YOLOv5 [PDF]
Jisuanji gongcheng, 2023 The existing image-based flame detection approach finds it challenging to balance real-time and precision, and it is incapable of accurately identifying small flame targets, making it ineffective for application situations such as small fire ...

Bistable swirled flames and influence on flame transfer functions [PDF]
Combustion and Flame, 2014 Large Eddy Simulations (LES) are used to study a lean swirl-stabilized gas turbine burner where the flow exhibits two stable states. In the first one, the flame is attached to the central bluff body upstream of the central recirculation zone which contains burnt gases. In the second one the flame is detached from the central bluff body downecirculation

Study on Unstable Combustion Characteristics of Model Combustor with Different Swirler Schemes
Energies, 2022 In this paper, the effect of the swirler scheme on combustion instability is studied. Through the proper orthogonal decomposition (POD) of flame images, Abel inverse transform and other methods, the influence of swirl intensity on the characteristic ...

Design and Decomposition Analysis of Mixing Zone Structures on Flame Dynamics for a Swirl Burner
Energies, 2020 The recirculation zone and the swirl flame behavior can be influenced by the burner exit shape, and few studies have been made into this structure. Large eddy simulation was carried out on 16 cases to distinguish critical geometry factors.

Acoustic power measurements of oscillating flames [PDF]
, 1981 The acoustic power of an oscillating flame is measured. A turbulent premixed propane/air flame is situated near a pressure antinode of a standing wave in a laboratory combustion chamber. This standing wave is generated by a piston.
